> Yes. But earlier it was checking the wrong extended capability register.
For jessicah's case, the USB Legacy Support capability register was
located at 0x8460, but it was looking at 0x8480 and wrongly believing that
the controller is BIOS owned.
Agreed.
> The explore thread calls GetBusManager()->AllocateDevice(), which in
turn checks whether the newly connected device is a hub or a function.
AllocateDevice() was made virtual in
https://github.com/haiku/haiku/commit/319a3798bc05579e8be813c2524bc89864bae489,
and we (re)implement it for XHCI. As a result, Hubs were getting allocated
as devices. Also, we need to initialise the slot context accordingly for
hubs.
Completely forgotten that point! Thanks!
